01 / The question
How can projections recover an image?
Tomography reconstructs spatial information from projections. This project implemented and compared reconstruction methods on a Shepp–Logan phantom.
02 / The intuition
A mechanism worth testing.
Use a known test object to see what a reconstruction method preserves and what it distorts.
03 / The work
Inside the method.
Explore each part of the approach.
01Form the projection view
Radon-transform and Fourier-slice concepts connected the object to its angular projections.
02Reconstruct
Fourier-based reconstruction and filtered backprojection provided different computational routes.
03Compare outputs
Image-quality metrics and visual comparisons assessed the reconstructed phantom.
04 / The observations
What emerged.
The notes describe implementation and comparative validation on a known phantom, not clinical patient reconstruction performance.
This account is based on recorded project notes. Original reports, figures and datasets are not embedded here.
05 / The limits
Where the evidence stops.
Projection sampling, interpolation and filtering influence the result. The original phantom outputs and metric implementation are needed for quantitative comparisons.
